Biomedical equipment technicians, also known as medical equipment repairers, handle the complex medical equipment and instruments found in hospitals, clinics, and research facilities. This equipment is used for medical therapy and diagnosis and includes heart-lung machines, artificial kidney machines, patient monitors, chemical analyzers, and other electrical, electronic, mechanical, or pneumatic devices.

Technicians' main duties are to inspect, maintain, repair, and install this equipment. They disassemble equipment to locate malfunctioning components, repair or replace defective parts, and reassemble the equipment, adjusting and calibrating it to ensure that it operates according to manufacturers' specifications. Other duties of biomedical equipment technicians include modifying equipment according to the directions of medical or supervisory personnel, arranging with equipment manufacturers for necessary equipment repair, and safety-testing equipment to ensure that patients, equipment operators, and other staff members are safe from electrical or mechanical hazards. Biomedical equipment technicians work with hand tools, power tools, measuring devices, and manufacturers' manuals.

Technicians may work for equipment manufacturers as salespeople or as service technicians, or for a health care facility specializing in the repair or maintenance of specific equipment, such as that used in radiology, nuclear medicine, or patient monitoring. Approximately 40,090 people work as medical equipment repairers in the United States.
